hmhm. There is one meta question.
Why do we need ltt-control unloadability?
We expect merge lttng into mainline in nearly future.
At that time, Who need ltt core kernel module (not any specific probe).
IOW, why ca't we do following?
config LTT_TRACE_CONTROL
- tristate "Linux Trace Toolkit Trace Controller"
+ bool "Linux Trace Toolkit Trace Controller"
depends on LTT_TRACER
default m
help
If you enable this option, the debugfs-based Linux Trace Toolkit Trace
Controller will be either built in the kernel or as module.
